Effervescent oral composition

Abstract

The disclosure provides a multi-layered tablet configured for oral use, the tablet including a first layer including an effervescent composition and a second layer including a non-effervescent composition. The effervescent composition includes an effervescent material; one or more fillers in a total amount of at least about 30% by weight, the one or more fillers including at least one sugar alcohol; and at least one active ingredient. The non-effervescent composition includes one or more fillers in a total amount of at least about 30% by weight, the one or more fillers including at least one sugar alcohol; a binder; and a second active ingredient.

What is claimed is: 
     
         1 . A multi-layered tablet configured for oral use, the tablet comprising a first layer comprising an effervescent composition and a second layer comprising a non-effervescent composition, wherein:
 the effervescent composition comprises an effervescent material capable of causing effervescence in the oral cavity; one or more fillers in a total amount of at least about 30% by weight, based on the total weight of the effervescent composition, wherein the one or more fillers include at least one sugar alcohol; and a first active ingredient; and   the non-effervescent composition comprises one or more fillers in a total amount of at least about 30% by weight, based on the total weight of the non-effervescent composition, wherein the one or more fillers include at least one sugar alcohol; a binder; and a second active ingredient.   
     
     
         2 . The multi-layered tablet of  claim 1 , wherein the first and second active ingredients are independently selected from the group consisting of nicotine components, botanical materials, stimulants, amino acids, vitamins, cannabinoids, cannabimimetics, terpenes, nutraceuticals, pharmaceutical agents, and combinations thereof. 
     
     
         3 . The multi-layered tablet of  claim 1 , wherein the first active ingredient comprises a nicotine component. 
     
     
         4 . The multi-layered tablet of  claim 1 , wherein the first and second active ingredients comprise a nicotine component. 
     
     
         5 . The multi-layered tablet of  claim 4 , wherein the nicotine component is present in an amount from about 0.001 to about 10% by weight in each composition, calculated as the free base and based on the total weight of each composition. 
     
     
         6 . The multi-layered tablet of  claim 1 , wherein the one or more fillers comprise isomalt, polysaccharides, or a combination thereof. 
     
     
         7 . The multi-layered tablet of  claim 1 , wherein the one or more fillers comprise isomalt, glucose, and starch-derived polysaccharides. 
     
     
         8 . The multi-layered tablet of  claim 7 , wherein the one or more fillers comprise from about 60% to about 90% by weight of each of the effervescent and the non-effervescent compositions, based on the total weight of each composition. 
     
     
         9 . The multi-layered tablet of  claim 1 , wherein the particle size of the one or more fillers in the effervescent composition is less than about 35 microns. 
     
     
         10 . The multi-layered tablet of  claim 1 , wherein the effervescent composition, the non-effervescent composition, or both, further comprise one or more additives selected from the group consisting of flavorants, sweeteners, tobacco materials, taste modifiers, salts, binders, buffering agents, colorants, humectants, oral care additives, preservatives, disintegration aids, antioxidants, flow aids, compressibility aids, and combinations thereof. 
     
     
         11 . The multi-layered tablet of  claim 10 , wherein the particle size of any flavorants, sweeteners, taste modifiers, salts, binders, buffering agents, colorants, humectants, emulsifiers, oral care additives, preservatives, disintegration aids, antioxidants, flow aids, and compressibility aids which may be present in the effervescent composition is less than about 35 microns. 
     
     
         12 . The multi-layered tablet of  claim 1 , wherein the binder is a cellulose derivative. 
     
     
         13 . The multi-layered tablet of  claim 12 , wherein the cellulose derivative is a cellulose ether. 
     
     
         14 . The multi-layered tablet of  claim 13 , wherein the cellulose ether is hydroxypropylcellulose. 
     
     
         15 . The multi-layered tablet of  claim 1 , wherein the multi-layered tablet is substantially free of tobacco material. 
     
     
         16 . A composition for use in an oral product comprising at least two layered portions, the composition comprising:
 an effervescent portion comprising an effervescent material capable of causing effervescence in the oral cavity; one or more fillers in a total amount of at least about 30% by weight, based on the total weight of the effervescent portion, wherein the one or more fillers include at least one sugar alcohol; and a first active ingredient; and   a non-effervescent portion comprising one or more fillers in a total amount of at least about 30% by weight, based on the total weight of the non-effervescent portion, wherein the one or more fillers include at least one sugar alcohol; a binder; and a second active ingredient,   wherein the oral product is in the form of a tablet.
